Check is a unit testing framework for C. It features a simple interface for defining unit tests, putting little in the way of the developer. Tests are run in a separate address space, so Check can catch both assertion failures and code errors that cause segmentation faults or other signals. The output from unit tests can be used within source code editors and IDEs.
See https://libcheck.github.io/check for more information, including a
tutorial. The tutorial is also available as info check.
Check has the following dependencies:
- automake-1.9.6 (1.11.3 on OS X if you are using /usr/bin/ar)
- autoconf-2.59
- libtool-1.5.22
- pkg-config-0.20
- texinfo-4.7 (for documentation)
- tetex-bin (or any texinfo-compatible TeX installation, for documentation)
- POSIX sed
The versions specified may be higher than those actually needed.
$ autoreconf --install
$ ./configure
$ make
$ make check
in this directory to set everything up. autoreconf calls all of the necessary tools for you, like autoconf, automake, autoheader, etc. If you ever change something during development, run autoreconf again (without --install), and it will perform the minimum set of actions necessary.
$ mkdir build
$ cd build
$ cmake ../
$ make
$ CTEST_OUTPUT_ON_FAILURE=1 make test
Check uses variadic macros in check.h, and the strict C90 options for
gcc will complain about this. In gcc 4.0 and above you can turn this
off explicitly with -Wno-variadic-macros. In a future API it would be
nice to eliminate these macros.
